Read and write binary file in VBscript

I used earlier ADODB.Stream to read and to write binary file here is the link for that

How to concatenate binary file using ADODB.stream in VBscript

it works fine the only problem is ADODB.stream is disabled on windows 2003 server,

Is there another way i can read 3 files in binary mode and concatenate them or store them in one file in VBscript

thank you Jp
